Abstract:
Biological stability of the drinking water distribution systems refers to the potential of drinking water quality deterioration caused by the growth of microorganisms in the drinking water distribution systems. Accurate and reasonable evaluation of the biological stability of drinking water distribution systems is the premise to ensure drinking water quality safety. The common evaluation methods include predictive evaluation based on biological stability evaluation index and direct evaluation based on microbial abundance, activity and community composition. The influence mechanisms of hydraulic conditions, pipeline characteristics, nutrient substance, disinfectant and antibiotic resistance on biological stability in drinking water distribution systems should be deeply understood to formulate more effective control strategies. However, how to obtain representative environmental samples through actual pipe network sampling and experimental equipment research and how to use molecular biotechnology to obtain useful information are the main challenges in this research field. Therefore, the current situation of the research on the biological stability of drinking water distribution systems in three aspects: evaluation methods, influencing factors and control strategies were introduced. In addition, the main challenges currently faced by this field were discussed. Finally, the future development trend and possible research directions in this field were prospected.
